The scientific literature on COVID-19 is rapidly evolving and these articles were selected for review based on their relevance to Washington State decision making around COVID-19 response efforts. Included in these Lit Reps are some manuscripts that have been made available online as pre-prints but have not yet undergone peer review. Please be aware of this when reviewing articles included in the Lit Reps.<\/p>\n
Today’s summary is based on a review of 840 articles (817 published, 23 in preprint)<\/em><\/p>\n \t\t\t\t<\/p>\n Public health measures implemented to reduce SARS-CoV-2 transmission may have reduced the transmission of other seasonal respiratory viruses. In a retrospective review of medical records from health systems in Atlanta and Boston, average reproductive number (Rt<\/sub>) was found to remain above 1 for much longer in the past 5 seasons for influenza A, influenza B, and respiratory syncytial virus (RSV) compared to the September 2019-May 2020 season, which coincided with the COVID-19 pandemic. Declines in Rt<\/sub> in both locations in 2020 seemed to coincide with implementation of non-pharmaceutical interventions.<\/p>\n Sherman et al. (Nov 8, 2020).

Transmission chains in which the index case was a child were more frequently seen in household settings than school settings, although the authors recognize the limited number of studies within their review.<\/p>\n Suk et al.

At 22o<\/sup>C, the virus was stable on human skin, a $1 bill, and on clothing, for at least 96 hours, 8 hours, and 4 hours, respectively. At lower temperature (4o<\/sup>C) the duration of viral stability increased to up to 14 days, at least 96 hours, and at least 96 hours, respectively.<\/p>\n Harbourt et al. (Nov 9, 2020).

Of the 66 babies identified with SARS-CoV-2 during the study period, 17 (26%) babies were born to mothers with known perinatal SARS-CoV-2 infection, and only 2 (3%) were considered to have possible vertically acquired infection. The authors indicate that these findings support guidelines to avoid separating mother and baby after birth in situations where the mother has suspected or confirmed SARS-CoV-2 infection.<\/p>\n Gale et al.

Seroprevalence was not associated with the number of pets per household, which the authors suggest indicates that human-to-pet transmission was more likely than pet-to-pet.<\/p>\n Fritz et al.

The median duration of time for IgM seroconversion was 10 days, but seroprevalence declined steadily 4-5 weeks after symptom onset down to a 31% positive after 3 months. Meanwhile, median IgG seroconversion time was 11.5 days, and despite an initial decline, is observed in 92% of patients 3-6 months after symptom onset.<\/p>\n Maine et al. (Oct 27, 2020).

Nursing homes were classified according to a crowding index defined as themean number of residents per bedroom and bathroom. While the likelihood of SARS-CoV-2 introduction did not differ between homes with a low or high crowding index, each 1-point increase in the crowding index was associated with a 1.7-fold increase in incidence and 1.7-fold increase in mortality. Simulations suggest that converting all 4-bed rooms to 2-bed rooms would have averted 19% of cases and 18% of deaths.<\/p>\n Brown et al. (Nov 9, 2020).

They were also less likely to report being concerned about the potential to harm others by infecting them. Telling participants that others might think less of them for not following suggested guidelines did not encourage more entitled people to be more likely to follow them.<\/p>\n Zitek and Schlund.

In patients with no prior psychiatric history, diagnosis of COVID-19 was associated with increased incidence of a first psychiatric diagnosis in the following 14 to 90 days compared to other health events such as influenza or skin infection. Conversely, a psychiatric diagnosis in the previous year was associated with a 1.7-fold increase in the risk of a COVID-19 diagnosis, although this relationship may be confounded by socioeconomic factors.<\/p>\n Taquet et al.

Using CDC forecast data, the authors further estimate that this figure will rise to $5.7 trillion (roughly 30% of GDP) through November 2020.<\/p>\n Kniesner and Sullivan. (Nov 4, 2020).
